Answer:
Microarray technology is a very useful technology that allows to study the measure the expression levels of large numbers of genes simultaneously. It consists of a solid support (that can be glass, silice, or nylon), and to it are attached a lot of single stranded DNA fragments that acts like probes. By complementarity, the genes corresponding to this probes that are being expressed at some time will attach to it. Probe-target hybridization is usually detected and quantified by detection of a fluorophore compund, a silver stained, or chemiluminescence-labeled targets.
Answer:
The negative effects of the destruction on the global environment as well as on the local environment are the following :
1) If forests are destroyed for making commercial area, the habitat of animals are also destroyed.
2) Forest helps in the cleaning of environment by consuming carbondioxide and releasing oxygen. If destruction of forest occurs, the environment remains polluted.
